The Quaternary geologic map of Waupaca County, Wisconsin, provides details about the surficial sediment and landscapes that were formed underneath and adjacent to the Laurentide Ice Sheet during the late Wisconsin Glaciation (ca. 20,000 years before present). These landscapes include lowlands underlain by glacial and postglacial lake sediment, uplands composed of streamlined till (drumlins), meltwater-stream sediment, and modern sand dunes. Includes map, 8-page report, geologic logs, and GIS data files of the geologic map data in the geologic map schema (GeMS) format.
